A still further purpose 19 to provide a fluid pressure means to efl'ectlongitudinal movement of the nose-forming head.

A still further purpose is to provide a chuck for holding a cylinder ortank while a nose is being formed thereon, the chuck being of suchconstruction that the increas in pressure of the nose-forming head resuts in increased clamping effort by the chuck.

angular movement without depriving it of its longitudinal movement, sothat the tank or tube 'being operated upon may be rotated 0r spun by thechuck. This for the purpose of enabling the machine to be employed forthe nose forming operation on relatively large tanks where the movementof the nose forming head and the chuck as before mentioned would maketoo great a relative movement between the tank and the nose forminghead.

A still further purpose is to provide means for limiting thelongitudinal movement of the nose forming head to a prescribed len h.

A stillfurther purpose is to provide a supplementary work support to becarried on the bed of the machine between the and the nose-forming head.

A still further purpose is to provide a work ejecting means inconjunction with the chuck. p

A still further purpose seeks the rovision of a machine of thischaracter w ich may be conveniently operated by a single workman, sincethe driving means and the nose forming head advancing means are operatedby devices whose means ofcontrol can be concentrated at one point.

The-drawings illustrate and the specification describes apreferredembodiment of the invention and modifications of the nose chuck formingmechanism and the chuck mechaf nism, but -to none of these forms is theinvention to be restricted.

Referring to the drawings, and particularly to the preferred embodimentof the 1nvention, there is shown a bed A on which 1s mounted the noseforming mechanism B and the chuck mechanism C. The bed A is castpreferably in one piece consisting of the longitudinal side pieces 1,with the outwardly extending base flanges 2 to form a suitable base bywhich the bed may be supported. At the upper longitudinal edges, theside pieces 1 are inturned, forming the ways 3 on which all themechanism hereinafter described is mounted. As is usual with suchstructure, the bed A is formed w1th transversely disposed strengtheningribs .t which connect and are integral parts of the longitudinal sidepieces 1.

Beginning with the chuck mechanism, there are provided the pedestals 5and 6, 1n the former of which there is a bearing bushing 7, and in thelatter, a bearing bushing 8, each being held 111 its respective pedestalin any suitable way. The bearing 7 at the front end terminates in aplate 9 which acts as a wearing plate for the ball bearing 10, which isdesigned to take care of the thrust imposed upon the chuck by theoperations of the nose forming head. J ournaled in the bearings 7 and 8,there is a hollow shaft 11 and at the forward end of thlsshaft, thechuck is carried, the body 12 of the chuck. being secured againstangular movement on the shaft by the key 13. The chuck body 12 at itsrear is so formed that there is provided an annular flange 14 whichsurrounds the ball bearing 10. The face plate 15 of the chuck is made aninte ral part of the body and has projecting from its front face and atdiametrically opposite sides thereof, the arms 16, the facing sides ofwhich lie in converging planes, these lower sides converging from thefree ends of the arms toward the face plate 15. The arms 16 on theirouter sides are provided with the relatively wide recesses 17 from whichnarrow slots 18 open onto the inner sides of the arms. These slots andrecesses are provided for the purpose of holding the chuck jaws 19 onthe backs of which are formed the ribs 20 which are T-shaped in crosssection, the T-shaped ribs slidably engaging in the said slots andrecesses. The design provides for the backward movement of the jaws 19with respect to the arms 16, and since the inner faces of the latterconverge in the manner before described, the said backward movementoperates to move the jaws toward each other; The jaws are each providedwith an upstanding car 21 pcsitioned at the rearof the rib 20, and theseupstanding ears have formed therein, holes 22 which are relatively largediameter as compared with the headed studs 23 whidh through them andwhich connect with the base plate 15 by effecting threaded engagementwith the latter. Springs 24; surround the studs 23 nd are carriedbetween the cars 21 and the face plate 15. The springs tendv normally tokeep the jaws positioned at the forward ends of the arms 16 andtherefore operate to keep the jaws extended to the position for grippingthe greatest diameters of work within their capacity. The heads of thestuds act as a limiting means for the movement of the jaws 19.

The c'huck is designed for rotary move ment and to that end, there isprovided a spur gear 25 which is mounted on the hollow shaft between thebearing brackets 5 and (3. This spur gear is secured against angularmovement on the shaft by means of the key 26. A countershaft 27 isjournaled in bear ings formed in brackets 28 and 29 which are integrallateral 5 and 6 respectively. This countershaft carries a pinion 30which meshes with a spur gear 25. It also carries a spur gear 31 at itsrear end, and this latter spur gear meshes with a pinion attached to theshaft of a motor 33, the latter being carried on the bed A on which itis attached in any suitable manner. It will be observed that the rotarymovement of tihe motor 33 serves to communicate rotary movement to thechuck through the instrumentality of the two gear couples and thecountershaft 27.

The shaft 11 carries within its longitu'dinal bore, an e ecting rod 31commonly known a kickout rod. This rod is mounted for sliding movementwithin the shaft and through the face plate 15, a central hole beingprovided in the latter'to permit the ejecting rod to enter between thechuck j aws, the ejecting rod receiving a detachable head 35 at the endwhere it projects through the base plate.

projections of the pedestals The rod is designed primarily forlongitudinal movementv to e ect worlr pipe 41, the latter beingcontrolled by a three-way valve (not shown). The rear end of theejecting rod 34 is designed to receive a piston head 42 against whichthe water, or air or steam admitted to the cylinder acts.

The nose forming mechanism B comprises a nose forming head 43, a ram 44and driving mechanism 45. The ram 44 comprises a cylinder 46 with adetachable head 47 at its rear end. Passing slidably through thecylinder, there is a plunger rod 48 provided with a central longitudinalbore in which it carries the shaft 49, the latter connecting with thenose-forming head 43 and the driving mechanism 45. At either end'of thecylinder, there is provided a gland 50 which secures packing 51 v inplace to provide against leakage of the fluid admitted into the cylinderfor operating the plunger rod. The plunger rod is moved by the pressureof the operating fluid upon the piston 52 which is held onthe plungerred by means of threads formed thereon and a lock nut 53 set up againstthe'piston. Filler rings 54 are carried in either end of the cylinderand in surrounding relation to the plunger rod. These filler ringsaredesigned to'receive' the impact of the piston and are employed forthepurpose of limiting the stroke of the piston. Water or air underpressure or steam is admitted into either end of the cylinder for theoperation of the piston by means of pipes 55 which are controlledreferably by three-way valves, (not shown The forward end of'the plungerrod 48 terminates in an annular flange 56 by means of which it connectswith the nose-forming head 43, the latter being rotatably mounted in abearing pedestal 57 which is slidablymounted 'on the bed A, this pedesalresting upon the ways 3 and having a web 58 connecting its two supportinlegs, the web projecting underneath the anges forming the ways. Thus thepedestal 57 is maintained on the bed, but in such a manner that it maybe moved longitudinally along the bed. The body of the nose forming headis reduced in diameter where it is journaled in the bearing pedestal5'7, but behind this bearing pedestal, the body is enlarged into a cup'59, which receives the thrust ball bearing 60 and the flange 56 of theplunger rod 48. A. ring 61 in surrounding relation tothe plunger rod issecured to the cup at the open end by means of cap screws 62, the ring0'p-' erating to attach the plunger rod to the nose forming head withthe ball bearing 60 interposed between the two to care for the thrustimposed upon the head in the nose forming operation.

, The nose forming head shown in Figs. 1, 2 and 9, while not thepreferred form, is found convenient for the finishing operation, whereother machines equipped with the preferred form of head shown in Fig.

15 perform the operations preliminary to the finishing operation. ThlSfinishing head comprises a body of which the cup 59' and housing 63 areparts, these two portions of the body being connected by the reducedportion which is. journaled in the pedestal 57. The housing 63 is openat its forward end to permit the entrance therei'nto of the tube or tankbeing operated upon. The housing supports the nose forming rolls 64which are mounted for rotating movement with respect to the housing,being provided with trunnions 65 for th1s purpose. The axes of rotationof the nose forming rolls arearranged inthe form of a trihedral angle,the axes approaching each other from the open forward end to the rearend of the housing. I

The shaft 49 extends forward with the plunger rod 48 and eflectsconnection with the body of the nose forming head 43 to which it isfixedly secured.

The nose formlng head is given its rotary movement by means of thedriving mechanism 45, the latter comp-rising forward and rear pedestalbearings 66 in whichthe rear endof the shaft 49 is journaled, the latterbeing extended to the rear a suflicient distance for this urpose. Theshaft 49 is provlded with a spline 67 extending from its rear end to apoint aspecified distance therefrom. Between the two pedestal bearings66, there 13 mounted on the shaft 48, a spur gear 68 which carries a key69 slidably engaging the spline 67. This gear is thus secured againstangular movement on the shaft, but will fiermit longitudinal movement ofthe sha asis'necessary when the ram advances the nose forming head. The

Epedestals '66 both carry lateral projecting members 70 provided withbearings in which a shaft 71 is journaled, the latter carrying a pinion72 which meshes with the spur gear 68. The shaft 71 is driven by a motor73 whose shaft is common with the former shaft. The motor is mounted onthe bed A riphery. when the band is drawn tight around the fly wheel bythe movement of the hand lever 76, there being a toothed rack 77 withwhose teeth the lever can be made to engage to hold the band '75in-either tight 'or loose contact with the fly wheel.

An intermediate work support is rovided for tubes or tanks beingoperated upon and this work support comprises a body 78 which noseforming head is made to rotate.

is fixedly secured on the ways 3 of the bed A and is provided on its topface with a semicircular depression 79 formed to the radius of the tankor tube being operated upon. Piv-f otally mounted on one side of thebody 78, there is a lever 80 having an arcuate arm 81 which is designedto grip the tube or tank supported by the body 7 8 in the depression 79.The lever 80 is also provided with the straight arm 82 having anelongated slot 83 formed therein and having also a smaller eX- tendingarm 81 on which a weight 85 is carried, the latter being designed foradjustment longitudinally along the arm 84:. The lever 80 is operated bya ram movable either by hydraulic or pneumatic pressure or steam, andthis ram comprises a plunger rod 86 formed at its upper end with a fork87, the free ends of whose legs are inturned and enter the slot 83. Atits lower end, the plunger rod 86 receives a piston 88 which is interiorto and movable vertically in a cylinder 89, the latter as well as theplunger being mounted vertically on one side of the bed A, and thecylinder receiving its operat ing fluid through an inlet ort 90 withwhich a suitable pipe is connected for transmitting the fluid to thecylinder. As is the case with the other hydraulic members of themachine, the cylinder 89 is provided with a filler ring 91 to limit theupward movement of the piston.

It is obvious that the admission of fluid under pressure to the cylinder89 will operate to effect a gripping operation on the part of the lever80 with the tube or tank ield in the body 78; it is obvious also thatwhen the pressure of the fluid in the cylinder is relieved as it wouldbe in the case of the operation of the three-way valve which is designedto admit the fluid to the cylinder (the valve being not shown) that theweight 85 will operate to raise the arcuate arm 81 from the work held inthe body 78, thus permitting the removal of the work therefrom. Theweight is adjustable along the arm 84 to permit the propercounterbalancing effort to be obtained.

In Fig. 10, there is shown a modified form of chuck 92. This chuck isdesigned for stationary mounting on the bed A when the invention is soconstructed that only lthe he chuck is provided with stationary jaws 93with roughened inner faces 94 which are designed to engage and hold thetank when it is forced in between the jaws by the opera.-

tion of the nose forming head. The chuck is also provided with anejecting rod 95 Which carries a piston 96 movable in a cylinder 97 whichis made a part of the chuck, the operating fluid being admitted to thecylinder through an inlet 98 formed therein.

When it is desired to rotate the chuck alone, the invention may bereconstructed to have the nose forming head advancing means in the formshown in Fig. 13. When reconstructed along this plan, a cylinder 99 isappropriately supported on the bed A and in place of the shaft 48, thenose forming head is connected directly to a plunger 100 which entersthe cylinder 99 and connects with a piston 101 therein, fluid for theoperation of the piston being admitted to the cylinder at either end bypipes 102. Where the invention is constructed according to themodification shown in Fig. 13, the plunger rod 100 is secured againstangular movement in a bearing pedestal similar to the bearing pedestal57 which, of course, is designed to be positioned close to the noseforming head with which it moves longi tudinally along the bed A as aresult of movement imparted to it by the piston 101.

The preferred form of nose forming head, shown in Figs. 15 and 16 isused preferably with the advancing means shown in Fig. 13, since it isused to better advantage when held stationary. The head comprises a faceplate 102 which is secured against both angular and longitudinalmovement on the free end of the plunger rod 100. This face plate carrieson its face and disposed at angular distances 120 degrees apart thehousing members 103 which are made preferably integral parts of the faceplate, the housing members having only side walls which connect one withthe side wall of the adjacent housing member where these side walls cometogether in the vicinity of the center of the face plate. 011 the insideof each housing and on the opposite side walls thereof, there aremounted forward and rear bearing brackets 10 1, in which shafts 105 arejournaled, these shafts carrying substantially at their longitudinalcenters, the worms 106, and further carrying at their forward ends,where they project beyond the housing, the hand wheels 107 bymeans ofwhich the shafts may be turned.

Each of the housings 103 is designed to through appropriate holes formedin oppo- 1 site side walls of the housing 103 and are held in placetherein by screw caps 112 which close the holes through which thepintles are inserted. The cylinder is adapted for pivotal movement onthese pintles, so that the nose forming roll may have the.

axis of its rotation varied with respect to the face plate, and variousangular positions of the roll are obtained through worm arcs 113 formedintegrally with the cylinder 109, these worm arcs meshing with the worms106.. The roll 108 is provided with trunnions to permit its beingrotatably mounted in a yoke 114:, the yoke havin a projection 115 on itsback which slida ly enters an aperture formed in the closed end of thecylinder 109, the latter being formed with a relatively great thicknessof stock at the closed end, and the aperture conforming in shape to thecross sectional shape of the PIOJBCtlOIl, which is other than round, sothat there may be no relative angular movement of the yoke with respectto the cylinder. The cylinder 109 is closed by a cap 116 provided at itscenter with a hole with which a page 117 connects, this ipe beingdesignedto t water or air un er pressure or steam into the cylinder,wherein any one of these that is employed may exert a pressure on thepiston 118 to force the yoke radially in toward the axis of rotation ofthe face plate. The piston 118'is connected to the projection 115 of theoke by means of a plunger rod 119 which 1s suitably attached to both,but a spiral spring 120 surrounds the plunger rod and is compressedbetween the piston and the closed end of the cylinder. This spring tendsnormally to keep the piston near the open end of the cylinder, andthereby normally keeps the nose forming roll its farthest distance awayfrom the center of the face plate. Obviously the three nose formingrolls 108 will be moved toward each other by the admission of water orair under pressure or steam into the cylinders 109.

Also, it is apparent that the axes of the nose forming rolls may havetheir planes of rotation changed by the manipulation of the hand wheels107, since the turning of these wheels will result in the movement ofthe cylinders on their pivotal connections with the pintles 101. I

In the operationof the invention, it is only necessary to describe thepreferred embodiment, since the modified form, in the matter ofoperation, will be readily appar- 'ent from the description of thepreferred form. The tube or tank X on which the nose is to be formed isplaced first in the body 78 of the supplementary work support. If boththe chuck member and the nose forming head are to be rotated, the lever80 is adjusted just close enough to the tank to permit the latter to berotated in the work support. Both the motors 73 and 33 are then started,their direction of rotation'being such that the chuck and thenose-forming head will rotate in opposite directions. The admission offluid under pressure to the cylinder 46 at the rear end then serves toadvance the piston 52 toward the forward end of the cyllnder and-to movethe nose- 1 operation results in forcing the bottom of t e tank inbetween the jaws 19 of the chuck,

thus forcing the jaws backward with the result of increasing the bite ofthe jaws because of their consequent movement toward each other. Sincethe chuck and the noseforming head rotate in opposite directions, thetank is moved relatively fast with respect to the nose-forming head witha comparatively slow rotary movement of the latter, and the nose-formingrolls carried in the head are enabled to form the end of the tank intothe desired shape. It will be noted that as the pressure of the noseformmg head increases as a result of the forward movement imparted bythe ram 44, the bite of the chuck is increased, thus providing for anincreased hold on the tank with increased strain imposed by theadvancing of the nose forming head.

The operation upon the tank having been completed, the nose forming headis moved backward by the admission of fluid under pressure to theforward end of the cylinder 46, when the piston 62 and with it, the noseforming head are moved backward away from the tank. Thereafter, the tankmay be ejected from the chuck by the admission of fluid into thecylinder 37, the fluid acting upon the piston 42 to move the ejectingrod 34: against the bottom of the tank, thus forcing it from the chuckwhen the jaws 19 are moved to their normal position under the action ofthe springs 34.

In the event that the machine is to be used for forming the nose ontanks or tubes which are of larger diameter than it would be advisableto spin at such a speed as that at which the smaller tanks are spun, thebrake band 75 may be tightened on the fly wheel 74 by the properoperation of the .lever 76. Thus the nose forming head will be heldagainst rotary movement, but it may be advanced toward the tank to beoperated upon in the usual way.- When the nose forming head is thus heldagainst rotary movement, the relative -movement vbetween the tank andthe head is reduced in velocity, since the tank turns only as fast as itis moved bythe chuck.

When the preferred form of nose forming head shown in Figs. 15 and 16 isused, it is preferably with that form of ram shown in Fig. 13. Thecylinders 109 are connected to a source for furnishing water or airunder pressure or steam. Then as the nose forming head is being. fedforward by the'ram, the rolls 108 are moved radially in against the tankon which'the nose is being formed. After the completion of the noseforming'operation, the rolls 108 are moved since the rolls are movabletoward and away from each other.

While the invention is shown and described as a nose forming machine,it-is obvious that it may be employed for all sorts of formingoperations of similar character, simply by the employment of formingrolls of a properconformation.
